" winch the following is a specification.

ihis invention relates to headlights for locomotives, motor cars and similar conveyances and one ofthe principal objects of the invention is to provide means for automatically turning the headlights into the direct line of travel of the locomotive or other conveyance.

Another object of the invention is to pro vide one or more headlights for a locomotive, motor car or other conveyance and to provide means whereby when the locomotive passes around a curve in either direction, the headlight will be thrown directly inthe path f travel automatically, thus giving the engineer or motor-man a clear view of the track upon both sides and in rounding L another object of the invention is to nple, reliable and efiicient means otally connecting the headlight or its to the front axle of the locomomotor car, so that the movement of 2. in rounding curves will move the heat. ght to a direct line of travel of the locou'iotive or motor car without attention on the part of the engineer or motorman.

These and other objects may be attained means of the construction illustrated in th accompanying drawings, in which;

1 are 1 is a. side elevation of a motor car its. headlights constructed. and unie' in accordance with this invention; is front end elevation of the ear; iv is a vertical longitudinal sectional view of the front end of the car; Fig. 4c is a top plan view of the same; and Fig. is a bottom plan view.

While 1 have shown in the accompanying rawings my invention as applied to a mo car, it will be understood that the same similar construction may be placed 1 on a locomotive or other similar convey without'departing from the spirit or e of the invention as defined in the ns e1 ing to the drawings, the numeral 1 gnates a motor car which. may be of the Specification of Letters Patent.

usual or any suitable construction and 2 are the front wheels supported upon a bolster 3, said bolster being pivoted at 4 underneath the front end of the car. The wheels 2 and 5 are mounted on the front bolster 3 in the usual or any suitable manner. When. the car is rounding a curve on the rails 6, the bolster 3 will turn on its pivotal point 4:.

Connected centrally to the bolster 3 is a bar 7 which extends toward the front of thecar and is provided with a longitudinal slot- 8. Pivotally mounted in the slot 8 is a stud or pin 9' formed on or connected to a lever 10, said lever being pivoted centrally at 11 upon a boltor rod 12 and said lever being held in place by means of stop nuts 13 on opposite sides of said lever. The front end of said lever is preferably tapering in form and provided with an upwardly extending stud or pin 14' which extends through a slot 15 in an angular support 16, said support being mounted to rotate freely in a keeper 17 on the front of the car 1, and said support 16 has attached to its upper end the headlight 18.

rod 26 extending down through the front end of the car. In order to render the throw of the link 22 adjustable, a set screw 27 is mounted in a bracket on'the end of the arm 25, said set screw being mounted in a lug 28 on the sliding block 23. The arm 25 is provided with a bearing boss 29 and is securedto the vertical rod 26 by means of a binding screw 30. The lower end of the rod 26 is bent at right angles, as at 31 under the front end of the car and a link 32 is pivoted at one end of the foot 31 while the opposite end is pivoted at 38 to the lever 10. Thus the movement of the bolster 8 actuates both in either direction.

The operation of my invention may be briefly described as follows: When the locomotive or car rounds a curve in either direction the turning of the bolster 3 will, through the various connections described, reflect the light immediately in the center of the track lights automatically upon rounding curvesto give the engineer or motorman a full view directly in front of the locomotive or car without any attention on his part.

From the foregoing, it will be obvious that a headlight made in accordance with my invention is comparatively simple in construction, may be applied to any locomotive, motor car ortsimilar conveyance without great expense in installing the same, that the op.- eration of the light is entirely automatic, requiring no attention on the part of the engineer or motorman, and that the entire device is comparatively simple in construction and not liable to get out of order.

I claim:

v 1. An automatically operated headlight for locomotive or 'motor cars comprising a front bolster pivoted to the car, an angular support for a lamp in front of the car, pivotal connections between said support and the bolster for turning said lamp in the path .to be traveled by the car, a lamp mounted on said angular support, a lamp at the top of the car, and connections between the upper lamp and said bolster for turning said lamp simultaneously with the first. mentioned lamdp of the car, an an ular support for the front lamp, a front b0 ster pivoted under the car, a lever pivotally connected to the car, a bar connected to the bolster, said lever being pivoted to said bar, and connections between the top lamp and said lever for. turning both lamps simultaneously in the same direction to cast the light rays inthe path of travel in front of the car in rounding curves.

In testimony whereof I aflix my signature i in presence of two witnesses. w
